Some people are skeptical this technology can ever work, but it appears CASIC’s Phase 1 testing in a 2km tunnel has given them the confidence to proceed to Phase 2 testing in a 60km long tunnel.
Chinese railway engineering leads the world so I have a hunch that if any nation can pull this off, then it’s China. However, lots of questions remain. A back-of-the-envelope calculation says that to achieve those speeds in the 2km test tunnel deceleration would have been about 3G. That’s the same as a rocket at lift-off and not many people’s idea of comfort.
